What Are Whole House Water Filters?
Whole house water filters are systems designed to filter water for the entire house --- not just a single sink.
In my experience as a home inspector, the most common water filters are for the kitchen sink and the refrigerator water filter. These point of use of water filters are designed for a single fixture or appliance.
In contrast, a whole house water filter will filter a home's water for every shower, sink, and appliance in the entire home. The main use of a whole house water filter is for smell and taste.
The municipal water filtration plant already has standards for safe drinking water --- though how much you trust the government standard is up to you.
Anyways, whole house water filters are largely designed to reduce chlorine, chemicals, and sediments. Some whole house water filters also have ultraviolet lights to kill microbes. And the main maintenance requirement of whole house water filters is periodically changing the filters.

What Are The Benefits Of A Whole House Water Filtration System?
Before any homeowner decides to install a whole house water filter, it is good to know some of the benefits that can come with using one. These benefits include the following…
Although chlorine is used to disinfect drinking water and is safe at an appropriate level --- it can lead to poor tasting water. Poor taste is the number one reason people invest in water filtration systems --- just make sure the filter explicitly states that it improves taste.
Hair & Skin
Chlorine can also have a negative affect on skin and hair for sensitive individuals. This is the main reason why shower head filters are becoming so popular which is not necessary if you install a whole house filtration system.
Often times, seeing dirt or particles in water is irritating to most people even if the water is safe for drinking. Installing a whole house water filter ensures that particles such as dirt, rust, and sand are removed from the water from the main source. Rust and other particles may eventually damage copper piping as well through scouring.
Some whole house water filters feature UV light systems which are designed to disinfect the water as well as filter it. These types of systems are more appropriate for homes with well water.
A whole house water filter can minimize or eliminate off smells such as sulfur or chlorine from your water.
Some whole house water filters are designed to filter heavy metals such as lead and mercury. Lead is a scary thing, and even "acceptable levels" of lead in municipal water isn’t acceptable to everyone. A whole home water filter can greatly reduce the amount of lead in your water.
How to Install a Whole House Water Filter?
Even though installing a whole house water filter can be a DIY job, for most homeowners, it is advisable to hire a competent plumber to install it. Buying the product yourself will usually save money, and then you just pay for labor.
Most whole house filters already come with the fittings, water shutoff valves, and other components needed to install the filter system.
Here is a quick breakdown of how to install a whole house water filter...
Step 1: Find the right location for your water filter. A whole house water filter is usually installed AFTER the main water shutoff (and water meter). You may want to install the water filter after it branches for the exterior hose bibs.
It's advisable to install it in a location that is accessible so you can easily change the filter.
Step 2: Shut off the main water supply
Step 3: Open a faucet at the lowest possible point in the home to drain all the water left in the pipes.
Step 4: Cut and remove the pipe section for the filter using a tubing cutter. Make sure the length accounts for the whole system including any valves and fittings.
Step 5: Smooth the ends of the newly cut pipes
Step 6: Install the shutoff valves on both ends
Step 7: Mount the whole house water filter using the manufacturer provided bracket and bolts (and seal any threaded ends using Teflon tape to prevent leaks).
Step 8: You will need to solder or glue the pipe joints. If you use push fittings, you may not need to.
Step 9: Turn water back on. Now it's time to flush the system with cold water from a faucet. If you have a carbon filter, run the water until the dark water (carbon dust) goes away. You may also see cloudiness for a day or two which are air bubbles from the carbon filter and is normal.
How To Pick The Best Whole House Water Filter?
Before you purchase a whole house water filter, there are certain things you will need to consider in order to select the best one. Things like…
Present Water Quality
For instance, if your water is provided by municipal services, then you may want to focus on improving the taste and removing any odors. If your water source is from a private well, then the water may have high levels of chemicals, pesticides, or heavy metals such as iron.
Some whole house water systems can exceed one thousand dollars, but others can be purchased for less than $100. If you need just a basic sediment filter that can improve water taste, then a cheaper filter may be your best option.
Before you purchase a whole house water filter, it is essential to know the flow rate of the filter and of your household. The flow rate is the amount of water used as gallons per minute. The average whole house filter flow rate is in the 5-15 GPM range.
If your family uses 30-GPM, and your filter is rated for 10-GPM, then there will be a significant drop in water pressure during peak water usage. Try to determine your households GPM during peak water use by adding up all of your plumbing fixtures flow rates in use (look for the GPM data on the back of the toilets, vanities etc.)
Filter Size & Longevity
There are various sizes of whole house water filters available. A large filter can service high water supply and have a long service life. Some filters are made to last for up to 10 years without changing. There is usually still a pre and post filter requiring more frequent changes.
Great whole house water filters are certified by NSF or ANSI. This is because they comply with quality standards and specifications.
How Are Whole Home Water Filters Different From Other Systems?
It was reported by North Dakota State University that the major home filtration products are sediment filters, activated carbon filters, and mixed media. Most home water filters employ one or a combination of these filters and they are mostly used because of their efficiency and range of use when compared to other types of filter.
For instance, while reverse osmosis (one of the most widely used filtration systems) is convenient and effective for water filtration, it is used only at the point of use, specifically under the sink.
This means that every other source of water in the house is not filtered. Also, it is more costly to have the reverse osmosis filtration systems installed at every nook of your house than having a single filtration system.
Apart from the points mentioned above, whole house water filtration systems have high flow rates (thousands of gallons of water per day). In general, a whole house water filter may significantly reduce cost over the long run, and also easier to maintain.
Where To Buy The Best Whole Home Water Filter?
There are many outlets—both online and offline—that sell whole house water filters. However, it is important that when you want to buy your water filter, you should look for a place that sells quality whole house water filters.
In my opinion, Amazon is a great market to find a whole house water filter because you can choose from a variety of products, and read an extensive amount of customer reviews. Amazon also has a great return policy, and shipping is usually very fast…sometimes free.
